Upper Midwest and Northeast

Scattered moderate and locally heavy flights that began the weekend quickly grew to more widespread moderate to heavy flights in the wake of a cold front. With this frontal passage, high pressure followed by Monday and just as quickly quieted migration activity to locally light to moderate flights. However, another change of air mass brought favorable migration conditions on Tuesday and Wednesday nights to the region, and spawned moderate to heavy flights first in the Upper Midwest and then farther east across the remainder of the region respectively. By Thursday night locally moderate and heavy flights are primarily distributed east of the Appalachians.

Gulf Coast and Southeast

A frontal passage brought moderate to heavy flights across much of the region for Saturday and Sunday nights. The days that followed did not achieve the intensity and extent of these weekend movements; however, light to moderate flights were evident in many areas across the region. Some of these were locally heavy, particularly Monday night in the Carolinas and Tuesday night in the Florida Panhandle.

Great Plains

Moderate to heavy flights occurred in staggered waves for the weekend, first in the northern and central Plains, then in the eastern and southern Plains, and then again in the northern Plains, as favorable migration conditions built in and through the region. This pattern continued for the beginning of the work week, but without the extent of the weekend flights. As a strong disturbance, with intense rain and thunderstorms, pass through the region to end the period, locally moderate to heavy flights followed in the clearer and cooler air building in from the west.

West

Moderate to locally heavy flights kicked off the weekend on Friday night and ended the period on Thursday night, with larger flights evident particularly in the Rockies. In the interim light to moderate flights were widespread across the region, although tamped by scattered precipitation. Note that some areas that are often active with migrating birds on radar, such as the Central Valley, continued to show modest movements during this period.
